firmware: using built-in firmware ql2200_fw.bin

Please note, the linux kernel is GPL, the qla2xxx firmware is NOT. That means you may not redistribute the resulting kernel image.
However, you may redistribute both, the linux kernel(source) and the firmware seperatly(under the terms of their licences) and provide instructions to others on how to compile it._________________Black Holes are created when God divides by zero!
